Help with settings when upgrading to v3 MS1 board and 4bar

Post by etx »

Hey Guys,

I think my resetting issue is due to the car running very rich and backfireing under boost. Off boost it runs fine, but once I hit boost my AF goes down to about .6vdc! Super rich, off the scale. So, I just double checked my MAP settings, everything seems right. When the motor is off it reads 101kpa. I set the 4bar setting in the settings.ini file for Megatune, and selected 400Kpa Map sensor in Megatune. Before all this I was running the v2.2 board, but I upgraded to the v3 so I would have the flyback circuit and went for the 4bar map. So I copied all the settings from my v2.2 to v3 by hand and double checked everything. All settings are the same with the exeption of the Map sensor. Only thing I can think of is the scaleing is off somewhere. I've attached my VE map just for referance.
